Brushing – Is a kind of surface treatment method which forms lines on workpiece surface by grinding products and plays a decorative effect. Suits to mainly metals, such as aluminum, steel, stainless steel, brass, titanium, etc.

What’s the function of Brushing?

1. Make the metal surface obtain non-mirror metallic luster;

2. Cover up the production of mechanical lines and mold defects;

brushed finish

Electroplating – Is the process of plating a thin layer of other metals or alloys on the surface of some metals by using the principle of electrolysis. Common electroplating types including: Zinc plating, Nickel plating, Chrome plating, Gold plating, Silver plating, etc. Suits to mainly metals, such as aluminum, steel, stainless steel, brass, titanium, etc.

What’s the function of Electroplating?

1. Prevent metal oxidation;

2. Improve wear resistance, electrical conductivity, reflection, corrosion resistance;

3. Make the surface beautiful.
